If the car won't start after being parked for two days, it might be due to a dead battery. Here is some information about car battery drainage: 1. Introduction: After prolonged parking, a normally functioning vehicle may have difficulty starting. 2. Definition: The battery automatically charges while driving. When the vehicle is idle, the battery still experiences discharge. However, the extent of discharge varies depending on the battery model, usage time, and type. Therefore, it's necessary to inspect your battery based on its specific condition. 3. Prevention tips: During prolonged vehicle inactivity, it's advisable to check the battery every two weeks. For instance, inspect the electrolyte level - generally, the electrolyte surface in the battery should be 10-15mm above the plates. If insufficient, promptly add distilled water.
